Lass, Do you think he may need to see some of the consequences? I think he is getting complacent and it may be time for him to see what he may be missing out on. IOW he might need something scarier than a Counseling Outburst to be able to break through his fear of initiating.
I don't know what they should be, but he's been coasting for a year now making small steps but not really pushing himself all that hard. Just some food for thought.
Have you ever told him what your ultimate goal is? Such as, I want to work towards ML once per week.
From an outside view, I think your H is a lot more horny than he lets on. He just prefers that you force him into it, for some weird reason. If you don't do that, he takes care of it himself. That is my gut feeling. Of course, I could be waaaaaay wrong. Do you know how wrong I am about my own husband? A lot!!
